In LTE, radio resources are divided into time and frequency resource elements. Resource elements in time axis are divided into number of OFDM symbols and in frequency axis are divided into number of sub-carriers . Resource element (RE) is a smallest resource unit, which occupies a single sub-carrier and an OFDM symbol.
Read moreHow are resource blocks calculated?
For 50 Mbls one has to assign x blocks= (50/100.8)x total no. of resource blocks(100)= one has to assign 50 resource blocks, and in case of 60 Mbls the number of assigned RBs= (60/100.8) 100=60. In one second the transmitted bits will be 50Mbits and 60 Mbits respectively.
Read moreWhat are resource blocks?
A resource block (RB ) is the smallest unit of resources that can be allocated to a user . The resource block is 180 kHz. wide in frequency and 1 slot long in time.
Read moreWhat is a resource grid in 5G NR?
5G NR physical layer uses time-frequency resource (physical resource block) for transmission. A resource grid consists of N size,μgrid,x subcarriers and N subframe,μ symb number of OFDM symbols (Table 2 and 3).22 Şub 2022
Read moreWhat is virtual resource block in LTE?
The E-UTRA uses the concept of VRB (Virtual Resource Block) when allocating resources . It defines two types: LVRB (Local Virtual Resource Block) – this is the same as the PRBs; DVRB (Distributed Virtual Resource Block) – this identifies a distribution of the resources required over a number of PRBs.
Read moreWhat is RBG in 5G?
RBG is the resource block group size when PDSCH has resource allocation type 0 . Type 0 resource allocation has distributed PRB allocation for UE. This distribution is based on the PRB group. PRB group size depends on BW.
Read moreHow are resource blocks allocated in 5G?
In 5G NR, similar to 4G the resource allocation is done in Time domain and frequency domain . Time domain resource allocation defines which symbols are allocated to UE and frequency domain allocation defines which RBs are allocated to the UE.
